Deploying the new Cisco 9800-CL wireless controller is fast and easy, and by using the built-in workflows, a new wireless network can be deployed in only a few minutes. In this post, I’ll review how to deploy the virtual wireless LAN controller in VMware ESXi and stand up a very simple WLAN. We’ll also take a look at some potential gotchas and some noteworthy differences between how the new WLC is configured compared to the AireOS WLC.
A phrase that really bothers me is “not my problem.” Usually I hear it in conversation with someone who learns of a problem but immediately seeks to absolve himself of any responsibility for the cause or responsibility to help.
I believe a networking professional, whether in pre-sales or working in the field, should have a deep understanding of networking concepts and strong technical experience. But also important are the soft skills necessary to build trust with customers, encourage strong relationships with account managers, and develop camaraderie and collaboration among teams. The words “not my problem” undermine those relationships and therefore shouldn’t be on the lips of a networking professional, let alone any sort of professional.
Only a few years ago, Cisco tried their hand at a converged access wireless platform with, among other devices, the Cisco 5760 Wireless LAN Controller. To this day, I have nightmares about that box. It wasn’t fully functional, and it had huge code issues. Today, in spite of AireOS being a stable, highly functional, and well-known WLC platform, Cisco is trying it again with a range of WLCs in the 9300 and 9800 series.
However, will this brave attempt prove to have the same fate as the 5760?
